RepairPal Expert Overview
Our Quick Take:
The rear axle may lock up (stop turning) unexpectedly and cause a loss of vehicle control and/or a vehicle crash.
What Should You Do?
Chrysler will notify owners of affected vehicles beginning in November, 2012. If you notice an abnormal noise from the rear axle, or you don't receive notification and you feel you should have, please contact your dealer. It’s helpful to have your vehicle identification number (VIN) handy when you call.
The rear axle pinion nut may loosen due to a lack of adhesive. If the rear axle pinion nut loosens, the axle can lock up and cause a loss of vehicle control and/or a vehicle crash with little warning. Dealers will install a pinion nut retainer to correct this concern. The Chrysler recall number is M34.
